OK, here is a link for my last post. I would add it to the post but I don't think I can edit it any longer. I am looking at postings from June of 2007 but, how odd is this, I am having similar (not exactly the same) problems in my brand new 2009.
 
What a mess.

    Try maintaining constant pressure during turns by vsaxena

"To improve mileage, it also will try to anticipate when you are trying to brake/stop and reduce fuel flow. During a turn many drivers tend to reduce the pressure on the gas pedal. This is not a conscious decision but happens with everyone. If you are taking off from a stop, and turning, and reduce the pressure on the gas pedal, the car might be anticipating that you are about to brake. The electronic throttle might be reducing the gas flow, in anticipation of the brake. So try and keep constant pressure on the gas pedal during turns."
 
============
 
Why does the X3 require this much fine tuning OF THE DRIVER? Blame the customer, blame the driver is all over these threads.
 
My car, sometimes but not every time, slows itself down to nearly a stop on turns. So sometimes it understands that you are slowing down and sometimes it does not?
 
Is the X3 just that stupid?
 
90 degree turns are generally done at the same speed, you do not take a turn at 50 mph for example. So when does the X3 decide to brake itself and when does it not? Is it the incline? Is it how fast it was going a few minutes ago? Is it the ambient temperature? What exactly causes the X3 to decide to brake itself sometimes but not at others?
 
Is the X3 just that stupid?
 
My X3 also jerks when accelerating slowly. When accelerating quickly it is much more smooth. So the answer is to lead foot it and hope you do not hit something? The answer is to continuing accelerating into turns and hope you do not hit something?
 
So my X3 can only be driven dangerously? You can get better gas mileage but you have dramatically increased the risk of hitting something?
 
What?

2007 X3 Transmission Problem by pjd5

2007 X3. Just took delivery two days ago. Forget hesitation between gears - all the posts I've read seem like child's play compared to what happened to me last night! While driving, it just slipped completely out of gear - as if it were in neutral. No gears engaged AT ALL! Only revving engine. This happened at a stop light with cars behind me, but I think it slipped out of gear even before I came to a stop. I put it in park and then back into drive and that didn't seem to do anything - still just a revving engine. Probably after maybe 5-6 seconds (seemed like an eternity, actually), it went into gear, and I was able to pull away from the stoplight. The transmission malfunction light went on and stayed on, but the car seemed fine. Then I got to my destination, parked it, turned it off, came back out 5-10 minutes later, started it up and the transmission malfunction light was no longer on. Drove okay on the way home. Anyone else ever had this happen????????? Taking it into the dealership today....

Mine is an ultra crappy transmission and drive "quality" that BMW says it's normal and cannot do anything else for me. But looks like your's is a malfunction. Can we hear your purchase process? Did you do any DD on this. Did you do any research in the internet? Still wish they can fix it for you though. Good luck!

Due Diligence?
 
Stop blaming the customer. Why is it your fault or my fault or his fault for this psychotic transmission. Blame BMW for making this ridiculous car AND for saying that this is normal. Normal?
 
The only reason to buy a BMW is for its ride. The X3 does not have the ride so it is an over priced, under performing HOJ.

New glitch by pp2009pp

This is new. Going uphill at 20 mph, push accelerator down - no acceleration, push down harder - no acceleration, tachometer suddenly springs up and down between 2 and 3K and acceleration commences.
 
Bizarre.

None of these problems are new. Quit posting over and over again and go do something. I posted detailed circumstances so that people would NOT fall into the same problems I had. The 2007 was a brand new vehicle when I bought it so there was no prior issues. Had you read any of the thousands of posts people have made since then, over multiple web sites you might not be in the trouble you are in. That is Due Diligence.Now go get a Lemon Lawyer, decide what you want (buy back or trade assist) and take it from there.
 
Sorry, you are having these problems, but we cant resolve this--you can. And we have now told you how!

I totally agree. It is a waste of time posting the same issues over and over again. Its is simple, if you are not happy with the problems these vehicles have you need to do something about it YOURSELF.
 
Now one is going to wave a magic wand and it is all going to be fixed for you, I KNOW. It took me getting off my backside and starting legal action and after long months of headaches and lots of evidence and finally the problem was gone!
 
My fight was with BMW in another country and we don't have the protection of lemon laws like you guys!
 
Im not having a crack here at anyone, but you need to understand that BMW as a company are NEVER going to admit there is a fault, they are one of the most arrogant companies around and could not give a f%^k about their customers, only their bottom-line!
 
These people who come on here and who are still considering buying one must be totally mad.....YES THESE LATEST CARS STILL HAVE THE ISSUE, BMW wont make a special X3 for you to buy that wont have the problem if you buy one.
 
Sorry but I have been watching this thread for so long now and its the same thing over and over.

Acceleration problems with lower ambient temperature by pp2009pp

Actually, that acceleration failure is new to me. That is fact. People are always entitled to their own opinions but not their own facts.
 
The entire point of threads such as these is to see what others have experienced and to see what the solutions are. Otherwise, they are useless. Most of the threads on these and other forums are talking about the 2007s and 2008s as if the problems WERE FIXED. Obviously, that is false and goes to the problem of DD.
 
Since temperatures have fallen about 30 degrees since I bought the X3, I am interested in finding out why acceleration failures appear to get worse with lower ambient temperature. If the problem is a s/w failure then why does ambient temperature affect the transmission problem? Isn't the s/w programming of gear shifts a function of speed and rpms?
 
If you do not have an actual answer to my probs then kindly ignore my posts. If you have an answer then I would appreciate that. Thanks in advance.

Hesitation on acceleration is normal by pp2009pp

So this is what it comes down to. The BMW X3's hesitation on acceleration is NORMAL for the car.
 
It isn't an issue, you just have to work around it because you the driver are less important than the car. So drive it in SD so that it doesn't get you hit when turning on an unprotected left or trying to merge into traffic or trying to avoid an accident. The stopping short while heading towards a stoplight or stop sign is also normal. The surge in acceleration is normal. It is all normal. It is designed to be this way.
 
Feel stupid yet?
